01 - Place chicken breasts between two sheets of plastic wrap and pound to an even ½-inch thickness using a meat mallet. Season both sides generously with salt and freshly ground black pepper.
02 - Arrange three shallow dishes: fill the first with all-purpose flour, the second with beaten eggs whisked together with 2 tablespoons of water, and the third with a combined mixture of grated Romano cheese and breadcrumbs.
03 - Dredge each seasoned chicken breast in flour, shaking off any excess. Dip into the egg wash, allowing the surplus to drip off, then press firmly into the Romano-cheese and breadcrumb mixture, ensuring an even, adherent coating on all sides.
04 - Heat olive oil and 2 tablespoons of butter in a large skillet over medium heat. Working in batches if needed, add the breaded cutlets and cook for 3 to 4 minutes per side until deeply golden and cooked through to an internal temperature of 165°F. Transfer to a warm plate and tent loosely with aluminum foil.
05 - Carefully pour off excess oil from the skillet. Add the fresh lemon juice and lemon zest to deglaze, scraping up any fond from the bottom of the pan. Stir in the remaining 2 tablespoons of butter and simmer gently for 1 to 2 minutes until the sauce lightly thickens and emulsifies.
06 - Return the chicken cutlets to the skillet, spooning the lemon butter sauce generously over each piece. Cook for 1 to 2 minutes to warm through. Garnish with chopped fresh parsley and additional lemon slices, then serve immediately alongside angel hair pasta or a crisp green salad.
